摘要:Interfacial space charge storage between ionic and electronic conductor is a promising scheme to further improve energy and power density of alkali metal ion batteries(AMIBs).However,the general behavior of space charge storage in AMIBs has been less investigated experimentally,mostly due to the complicated electrochemical behavior and lack of proper characterization ***,we use operando magnetometry to verify that in FeSe_(2)AMIBs,abundant li^(+)/Na^(+)/K^(+)(M^(+))can be stored at M_(2)Se phase while electrons accumulate at Fe nanoparticles,forming interfacial space charge *** and dynamics tests further demonstrate that with increasing ionic radius from li^(+),Na^(+)to K^(+),the reaction kinetics can be hindered,resulting in limited Fe formation and reduced space charge storage *** work lays solid foundation for studying the complex interfacial effect in electrochemical processes and designing advanced energy storage devices with substantial capacity and considerable power density.

摘要:理解电化学储能系统的构效关系将极大推动电极材料中新现象和新性能的发现与调控。然而,没有任何一种单一技术可以澄清电化学体系中复杂界面反应的所有问题,只有从多个角度进行观察才能看清被埋藏的界面和工作状态下的演变历程。由于大量储能材料富含过渡金属元素,其磁学性质与晶格结构、电子能带、电化学性能密切相关。因此,磁学测试分析可以揭示能源材料中的结构相变和局部电子分布等变化,解析物理化学反应机理,指导材料设计。围绕磁性表征技术,本文首先讨论了磁性测试的技术原理,随后总结介绍了磁性测试在研究电极材料物性结构表征以及电化学反应进程方面的研究进展,尤其介绍了原位实时磁性测试在阐明储能物理化学反应机理方面的独特优势。综合分析表明,原位磁性表征技术可以对电化学反应中的电荷转移进行高灵敏度、快速响应的测试表征,为揭示复杂界面电化学反应提供了新思路,在储能科学中具有广阔的应用前景。本文有助于了解磁性测试技术在电化学储能材料研究中的重要价值,并进一步推动磁性测试技术在储能领域的发展。

摘要:Numerical weather simulation data usually comprises various meteorological variables, such as precipitation, temperature and pressure. In practical applications, data generated with several different numerical simulation models are usually used together by forecasters to generate the final forecast. However, it is difficult for forecasters to obtain a clear view of all the data due to its complexity. This has been a great limitation for domain experts to take advantage of all the data in their routine work. In order to help explore the multi-variate and multi-model data, we propose a stamp based exploration framework to assist domain experts in analyzing the data. The framework is used to assist domain experts in detecting the bias patterns between numerical simulation data and observation data. The exploration pipeline originates from a single meteorological variable and extends to multiple variables under the guidance of a designed stamp board. Regional data patterns can be detected by analyzing distinctive stamps on the board or generating extending stamps using the Boolean set operations. Experiment results show that some meteorological phenomena and regional data patterns can be easily detected through the exploration. These can help domain experts conduct the data analysis efficiently and further guide forecasters in producing reliable weather forecast.
